The GT C’s rear end is also wider to fit the larger wheels and an active rear axle steering system carried over from the AMG GT R. Mercedes says it gives “significantly higher agility and increased driving pleasure with less steering input.”

The GT C also features larger front brakes. There’s also an extra “RACE” mode for the seven-speed dual-clutch transmission for faster shifting.

Both versions come with a fabric roof you can get in black, beige or red. It takes about 11 seconds to open or close it. And you can even do that going 30 mph.
